I am troubleshooting to see what is wrong with it. ___end___ Mon Feb 11 20:24:13 GMT 2013 MKIV End Patrol Mon Feb 11 20:35:29 GMT 2013 COMP End Patrol Mon Feb 11 20:35:42 GMT 2013 COMP Start Patrol Mon Feb 11 20:58:07 GMT 2013 MKIV Start Patrol Mon Feb 11 21:04:38 GMT 2013 MKIV End Patrol **MKIV PROBLEM COMMENT BY BEN**: Mon Feb 11 21:12:43 GMT 2013 Mk4 analog signal looks funny this morning. The pattern of humps occuors twice with the second read out shifted about 1/2 a waveform to the right. I think this suggests the o-scope is seeing the sync signal at the wrong time. I also noticed that the X1 led on the transform board durned off intermittently during this period. This LED indicates a HSYNCERR (when off) and in the past I have never seen it off. Now the O-scope looks good and some coronal signal can be seen through thick haze. I am not sure what changed to get the coronal and sync signals back to nonomial proformance. ___end___ CHIP COMMENT BY GREG: Mon Feb 11 22:50:29 GMT 2013 The problem with the Tek Temp Cooler is the RTD malfunctioned low which turned on the heater until it overheated. The temp controler resolves proper temp when RTD is simulated with a resistor. Also the chiller function is not operating properly. I belive the chilling function was not working before today. ___end___ Mon Feb 11 23:22:47 GMT 2013 MKIV Start Patrol Mon Feb 11 23:29:19 GMT 2013 MKIV End Patrol Mon Feb 11 23:34:29 GMT 2013 COMP End Patrol Mon Feb 11 23:34:31 GMT 2013 COMP Start Patrol MKIV COMMENT BY BEN: Tue Feb 12 00:03:01 GMT 2013 Barrel stopped moving at 242 when commanded to idle, console says Data Xfer failure done ___end___ Tue Feb 12 00:09:32 GMT 2013 MKIV Start Patrol Tue Feb 12 00:15:37 GMT 2013 MKIV End Patrol Tue Feb 12 00:16:32 GMT 2013 MKIV Start Patrol MKIV COMMENT BY BEN: Tue Feb 12 00:17:54 GMT 2013 Happened a second time in the CCW direction slowing to a halt at 239 ___end___ MKIV COMMENT BY BEN: Tue Feb 12 00:26:38 GMT 2013 Problem actually occours in both directions, barrel will rotate less then 360 degrees and stop. The observation will finish, akamai console will display a t_bdrive barrel glitch. Then when it is time to start the next observation we here a BEEP from nahenahe and the barrel continues to 180 in the directing it was going during the previous scan. After this is begins its new scan in the proper direction where it again stops early ___end___ MKIV COMMENT BY BEN: Tue Feb 12 00:32:18 GMT 2013 Rebooted akamai to see if this fixes the barrel issues ___end___ Tue Feb 12 00:32:47 GMT 2013 MKIV Start Patrol Tue Feb 12 00:39:03 GMT 2013 MKIV End Patrol MKIV COMMENT BY BEN: Tue Feb 12 00:40:32 GMT 2013 Still see the problem in some sans ___end___ CHIP COMMENT BY GREG: Tue Feb 12 01:06:46 GMT 2013 Tek Temp Cooler was left on so it will pump but the RTD input was left open so it will not temperature control ___end___ Tue Feb 12 01:43:59 GMT 2013 COMP End Patrol Tue Feb 12 01:46:25 GMT 2013: PSPT Abort Patrol CHIP COMMENT BY BEN: Tue Feb 12 01:48:58 GMT 2013 Colant final temp 103F ___end___ Tue Feb 12 01:57:23 GMT 2013 MkIV 00_09.rawmk4 17_37.rawmk4 18_00.rawmk4 19_54.rawmk4 20_18.rawmk4 00_12.rawmk4 17_39.rawmk4 18_03.rawmk4 19_57.rawmk4 20_20.rawmk4 00_16.rawmk4 17_42.rawmk4 18_06.rawmk4 20_00.rawmk4 20_58.rawmk4 00_19.rawmk4 17_45.rawmk4 18_09.rawmk4 20_03.rawmk4 21_01.rawmk4 00_22.rawmk4 17_48.rawmk4 18_23.rawmk4 20_06.rawmk4 23_25.rawmk4 00_25.rawmk4 17_51.rawmk4 18_27.rawmk4 20_09.rawmk4 00_32.rawmk4 17_54.rawmk4 19_48.rawmk4 20_11.rawmk4 00_35.rawmk4 17_57.rawmk4 19_51.rawmk4 20_14.rawmk4
